Io Moth Caterpillar

What kind is it?
Just wanted to know what kind of caterpillar this is. I live in Harford Co., Maryland. My husband found it on a green Japanese maple tree. It had already eaten a few limbs. Not sure if its a moth or butterfly. Thanks,

Hi Debbie,
The spines of the Io Moth, Automeris io, caterpillar are mildly poisonous. It is easily recognized because of the red and white stripes. The adult moths have eyespots on their underwings. They are small Silkworm moths, the male with yellow upper wings and female with brownish upper wings. They are sometimes found on corn and other garden crops.

  1. Way cool, I just found one in my rent in the eastern Montana region. Tongue river area is lush with cotton, ash and Russian olive trees; and I also seen a brownish mature praying mantis. It’s new for the area.
